TO ALL WHOM IT MAY CONCERN: I Be it known that I, HARRISON OGBORN, ofRichmond, in the county of Wayne, and State of Indiana, have inventednew and useful Improvements in a Combined Fanning-Mill. and Grain andSeed-Separator; and I do hereby declare the following to be a full andclear description of the same, sufiicient to enable others skilled inthe art to which my improvement appertains to fully understand and usethe same, reference being had to the accompanying drawings, making partof this specification, in which- Figure 1 is-a side elevation of myimproved'machine.

Figure 2 isa front elevation of the same.

Figure 3 is a section in line x 21:, fig. 2.

Figure4 is a detached view of my device for givingrotary andreciprocating motion to the screens.

Figure 5 is a top view, and A Figures 6 and 7 modifications of the same.

Similar letters indicate corresponding parts in the several figures.

The nature of my invention'consists, rst, in the use of a board slidingin grooves in side plates, in place of the customary hopper, and inarranging an adjustable swinging end board in such a manner that'theflow of the grain can be adjusted at pleasure by the position given tothe same by means of a cam-lever; secondly, in novel means of givingeither a rotary or cndwise or side motion'to the screens; thirdly, incombining with this appa+ ratus for giving motion to the screens, amovement for giving to the lower screen an up-and-down motion; fourthly,in providing the fan with a vertical circular partition rim, to directthe two currents of air coming in at each side of the drum into onestraight, strong blast; fifghly, in making the rear legs of the milladjust able, so as to give more or less pitch to the screens; andlastly, in making the screens adjustable, in sucha manner that theapparatus may, in a few moments, be so changed as to adapt itselfreadily to be used for cleaning either market or seed wheat, or smallseed of any kind.

A A, in my drawings, represent the upright of a fanning-mill, supportingthecross-pieces B B, and the sides G and drum D. Secured to thecross-pieces B B are the boards E, provided on theirinner sides with twogrooves, e e, in which the board F slides, and securely held together bythecross-piec'e G, over the top and under the bottom of which thegrooves e run, coming together in front at an angle, so that the board Fhas more of a slant in the upper groove e than in the lower one. Pivotedat its top, to the rear of the side boards E, at a, is v the swingingboard-H, which is adjusted by means of a cam-lever, E, and spur-pivotedat its front side, as

shown in Figure 8. I is the vibrating shoe, hung in the rear from thestandards A by the rods 6, and inii front'froi n the standards A bytherods 0. The inner sides of this shoe I are provided with three differentsets of grooves,

the'groovef running to the front end of the part I of the shoe I, thegrooves g running to the front end of the part I of the shoe, and thegroove in running the same as the grooves 9, but horizontally. Thesegrooves, with the exception of groove h, which is horizontal, convergetowards each other at the rear of the machine. In the grooves f slidetwo screens, the front one, J, being a fine square-meshed one, andthe-rear one, K, a coarser one, as are also the screens L sliding in thegrooves The groove it holds a board, M, which is not as wide as r thedepth of the part I of the shoe I. A long meshed screen, N, is supportedat its rear end by pins on its sides catching in ratchets 2' on theshoe, its front end resting on the bent portion, 11, of arod, 19, asshown in fig. 3. The screens K L and the board M are held in place andprevented from sliding out of their respective grooves, f, g, and h, bymeans of the pin f, passing through the staples f and through holes inthe screens, At the lower end of the part I of the sho'I, and restingagainst the front of its main part, is a trough, 1, across the wholewidth of the shoe, and directly under-the screen J, so that the smallergrains of wheat, chess,

cookie, &e., falling on to the upper grain-bottom, are shaken into thetrough, and from it are thrown outside of the machine. The rear sideboard z" of the trough I inside of the shoe-frame, is made adjustablebyhaving I holes in its bottom, sliding on pins on the bottom of thetrough. It is also provided with holes on its inner face,'correspondingin position with the holes in its bottom, sothat it can be placed in ahorizontal position, as shown in red lines in fig. 3. Inside of the drumD rotates the fan, its shaft 0 having its hearings on the stand: ards AA, andprovided with wear, to which" wings Q are attached. At its centreit, is provided with a circular rim, R, which acts as a guide to thecurrents of air coming in at each side of the drum, forcing themtogether in one blast under and through the screws L and the whole shoeI. At one side of the fanning-mill, just inside of the drum D, issituated a gear-whcel, S, giving motion to the shaft 0 by means of thepinion T, and operated by the handle U. At the opposite side, justoutside of its bearing on the standard A, the shaft 0 is provided with abelt-wheel, V, connected by a belt to the wheel W, which works loose onthe vertical pin 10 in the plate X, secured to the side 0. This wheel Wis provided with three sets of holes, k k H. Into one hole, 7c, isplaced a pin, on the under side of the connecting-bar J, which isattached to the side of the vibrating shoe 1, to which a horizontalcircular motion is imparted when motion is given to the wheels V W.Attached to the wrist 11, on the wheel V, is the rod m, linked to therod m, which is connected to the lever n on the rod 19. This rodp passesinto the fanning-mill, and is bent horizontally to the front, directlyunder the centre of the forward end 0 i the screen N, in such a mannerthat when the rodp is moved by means of the wheel V and rods m m, thclben 'lpartp' of the rod will strike the under side of the screen N,lifting it, and allowing it to drop again, thusi arting a quickup-and-down shaking motion to the screen; and as the lever n on the rodis pressed forward, and the part 17 is at its lowest position, resting on the lower grain-board D the crank-rod m is enabled to finish itsrevolution without pressing the part p" of the rod 1;, by means of itsbeing linked to the rod m, and thus enabled to bend. In place of thebelt around the wheels W V, I sometimes use a rod, 11, pivoted on thewrist v, the other end of which catches in either of the holes 7a or It,giving either a side or end motion to the shoe, instead of a. rotaryone, as'will be hereinafter more fully described The ends of thestandards A are made hollow, to receive square feet a a, which areprovided at theirlowcr ends with metal points, a Pins a",

passing through the end board the standards A, and the feet a, hold thelatter in position, so that the rear of the fanning-mill may be loweredor raised, according to the pitch desired for the screens. The end board0 is placed across the bottom C of the chess-box, and is provided with,an opening, 0 flush with the bottom C and closed by a door, '0. Throughthis opening the dirt, 860., can be cleaned whenever it becomesnecessary- The sliding-doors G G, over the openings of the drum, areprovided with cleats g g, which have pins 9 on their under side, to holdthemsecurely in any position in which they maybe placed, the pins 9preventing their slipping from their places through the shaking of thefanning-mill.

Seed wheat is cleaned in the following manner: The wheat is poured intothe slide F, on which, by reason of its being of equal width the wholeof its length, and not being narrower at its lower part, as it is usualto make the sides of square hoppers, the grain is spread out, thuspreventing any possibility of its clogging. The rear opening beingadjusted to the proper degree, by means of the tooth e of the cam-leverE being made to catch into the rack e, the grain is free to fall intothe upper end of the vibrating screen J. To regulate the flow of thegrain, it is only necessary to raise the cam-lever E, swing the board Heither nearer to or further away from the end of the slide E, and torefasten it by pushing the cam-lever E down; and to feed still fasterthan the utmost opening of the swinging board H will allow, it is onlynecessary todraw the board F out in the grooves. The screen J is themarket-wheat screen and as the grain is shaken down on it most of thesmaller wheat,,chess, cockle, and other impurities, pass through itsmeshes and fall on to the upper grain-board I, and

are carried into the trough P, from which they are shaken to the outsideof the fanning-mill, the wheat passing onto the screenK, provided withlarger meshes, bud falls through the same and the screens I on to theboard M, the screens K and L arresting all coarser impurities. Thisboard being provided with several holes to receive the pin f, can beadjusted nearer to or further from the rear end of the shoe, sothat asthe grain falls frouithe board on to the screen N, more or less of theremaining impurities are carried out by the blast from the fan The grainhas now fallen on to the lowest screen, N, which is provided with longnarrow cross-meshes, and which is constantly shaken by the rod p. Thesmaller wheat and any still remaining impurities are jolted and siftedthrough the meshes ofthe screen on to the inclined bottom of the shoe,from which they fall into the chess-box C, and may, whenever necessary,be taken out through the opening C whilst the large, pure seed wheat iscarried over the screen N and bottom grain-board D on to the floor underthe drum. To clean market wheat the screen N is taken out and laidaside, the screen J placed in its stead, the screen K taken out and alsolaid aside, and the board 2' of the trough I placed in the positionas'shown in red lines in fig. 3, thus forming g, continuation of theupper grain-board-I. To clean the finest seeds, such as timothy-seed,the sliding doors G of the drum are closed, and the screen J, in theplace of the screen N, exchanged for a finer one.

Having thus described my invention, what I claim as new therein, anddesire to secure by Letters Patent, is-

1. The trough I situated under and at the lower end of the uppergrain-board, with a removable side, 2', substantially as and fertilepurposes described.
